@Foogley , do you think a powered usb hub can help ? I do not have access to the bios (working pc).
Does someone know a usb.c powered hub that can work with windows and android, and can manage a good power supply for the ka3 ?
The idea is not to charge the pc with the hub (charging the phone can be a good point) but to give a good power supply to the ka3.
When talking about hifi, the power supply was something very important ; today, no one talk about it...

For hiRes with android, does someone try to modify lineageos to make the passthrough available natively in android for all the application ?

Many subjects in this thread, It could be a good idea to make a thread for each subject:
* stability of the usb power supply in windows and impact on the ka3
* hires with android natively : We know it works with uapp, but we need it for all android applications
* interference noises with some smartphone with 2G (?) : I bought a 1m usb-c cable in order to put the ka3 far from the phone, it's seems better

I'm not an apple users, so I do not list what's going wrong with apple, I let you add it to the list.

@alialex i have no idea, it's a latency issue that just stutters the whole system, i haven't really noticed it until i got usb to play sounds.

Dear friend,

Did you try to turn off the hardware mute switch option via the FiiO Control app for the KA3 after updating the firmware but the pop sound issue still remains?
(The device is embedded with a hardware mute switch, which can mute the impulsive sound that occurs when switching between tracks of different sampling rates. However, when the mute switch functions,it will also make a slight pop sound. You may choose to enable or disable it according to your preference.)

Best regards

Yes I did turned them off when I saw a review that mentioned about some minor pops every time it works. The problem still persists with or without it.

Any updates? If I don't play any sounds KA3 turns off, I have to change output to something else then back to turn it on.

Dear friend,

Does this issue happen in any certain condition? When connecting computer? Or the computer has entered sleep mode?

Best regards

I tried going to sleep mode and back and it didn't turn off. It turns off because it doesn't play sounds for a long time. (I already disabled USB power suspension, it's connected to my powered USB hub in my monitor that also has fast charge, it did the same thing when I plugged it in directly into my PC)

Edit:
I think it stopped turning off after I disabled dynamic power management in Fiio App.

Edit 2:
Aaand it turned off while I was clicking through videos.

Dear friend,

I attached the Foobar 2000 app I am using for you, please try whether it works?

Best regards

Yes, it works. Thanks!

Thanks for the feedback. Glad to hear about that.

I failed to reproduce this issue still, sorry.

USB cable recommendation for KA3: link
Shortest one (25 cm) is the perfect length. I feel much more confident when having KA3 in my pocket because of the angled connectors.

I use this 2 meter one to connect it to a xiaomi mibox and watch concerts on youtube and have good audio while lying on the couch.

Sunday clubbing with Ikko and Fiio . Nice synergy with these two. Ikko Audio OH10 and Fiio KA3.

Sennheiser HD6XX and Fiio KA3 on balanced out. Pretty ok and considering the KA3 price maybe even a great budget solution. But I prefer HD6XX more on tubes or some bigger amps.

Thanks for sharing!
